Sab nraum zoov FTTH Self-supporting Bow-Type drop Cable

Aipu-waton GJYXCH thiab GJYXFCH optical cable yog sab nraum zoov FTTH hneev-hom poob cable. Optical cable muaj 1 ~ 4 silica optical fibers nrog txheej, uas tuaj yeem yog G657A1 lossis G652D. Cov fibers kho qhov muag tsim los ntawm tib tus qauv tsim, cov khoom siv thiab cov txheej txheem yuav tsum tau siv nyob rau hauv tib batch ntawm cov khoom, thiab cov khoom siv kho qhov muag yuav tsum muab tso rau hauv nruab nrab ntawm cov khoom siv kho qhov muag. Optical fiber txheej txheej tuaj yeem ua xim. Cov xim ntawm cov xim yuav tsum yog xiav, txiv kab ntxwv, ntsuab, xim av, grey, dawb, liab, dub, daj, ntshav, liab lossis xiav raws li GB 6995.2, thiab cov fiber ntau tuaj yeem yog xim ntuj. Cov txheej txheem txheej, fiber ntau lub zog soj ntsuam qib, hom kab kab uas hla thiab qhov loj me, kev txiav tawm wavelength thiab khoov poob ntawm ib hom optical fiber ntau siv rau cabling yuav tsum ua raws li cov cai hauv Cov Lus 1, 2 thiab 3 hauv qab no. Cov tswv cuab lub zog hauv qhov kho qhov muag cable tuaj yeem yog lub zog siab stainless hlau xaim lossis phosphated steel hlau, lossis cov tswv cuab tsis yog xim hlau reinforcing ntawm polyester aramid hlau los yog lwm yam khoom siv fiber ntau, uas yuav tsum muaj txaus Young's modulus thiab elastic strain range. Cov tswv cuab lub zog ntawm cov kab hluav taws xob kho qhov muag yuav tsum yog 2 qhov sib luag thiab sib luag hauv cov kab hluav taws xob kho qhov muag. Ib tug tuab steel hlau dai hlau nyob rau sab yuav siv sij hawm qhov kev txhawb nqa tus kheej. Rau PVC sheathed optical cable, cov ntaub ntawv sheath yuav tsum ua raws li cov kev cai ntawm hr-70 "70 ℃ mos sheath qib mos PVC yas" nyob rau hauv GB / T 8815; Rau nplaim hluav taws retardant polyethylene sheathed optical cable, cov ntaub ntawv sheath yuav tsum ua raws li cov kev cai ntawm YD/T 1113; Qhov saum npoo ntawm lub sheath yuav tsum tiaj tus thiab du, thiab yuav tsum tsis txhob pom cov kab nrib pleb, npuas, xuab zeb qhov thiab lwm yam tsis xws luag ntawm nws seem. Cov xim sheath feem ntau yog dub, uas tuaj yeem ua tau raws li lwm cov xim xav tau los ntawm cov neeg siv khoom. Cov kab hluav taws xob kho qhov muag yuav tsum tau cim mus tas li rau ntawm lub ntsej muag, uas yuav tsum tsis txhob cuam tshuam kev ua haujlwm ntawm cov khoom siv kho qhov muag, thiab qhov kev ncua deb ntawm qhov pib ntawm cov paib nyob ib sab yuav tsum tsis txhob ntau tshaj 500m.
